Preferably, boss is four, is provided with a bolt mounting holes on each boss, is respectively the first bolt mounting holes, the second bolt mounting holes, the 3rd bolt mounting holes and the 4th bolt mounting holes; Double-screw bolt mounting hole is three, is respectively the first double-screw bolt mounting hole, the second double-screw bolt mounting hole, the 3rd double-screw bolt mounting hole.
Preferably, the first attachment face and the second attachment face are cellular structure, and this cellular structure is by triangle, pentagon and irregularly shaped composition.
Preferably, between the first attachment face and the second attachment face, be provided with the back-up block that connects the first attachment face and the second attachment face.
Preferably, between the boss of hold-down bolt, be provided with reinforced rib.
Preferably, the width of reinforced rib is 5mm-6.5mm, and reinforced rib is cross-like.
Preferably, the vertical distance between boss upper surface and the first attachment face is 0.7-1.2mm.
Preferably, the diameter of this bolt mounting holes and double-screw bolt mounting hole is 11mm.
The advantage that the utility model has compared to prior art is:
(1) the utility model, by design boss, has been avoided the foundry defect such as shrinkage porosite, sand holes that causes due to wall unevenness, thereby improves finished product rate and quality;
(2) by cellular structure design, alleviate the weight of mounting bracket, reduce the quality of complete machine, be indirectly conducive to the reduction of complete-vehicle oil consumption;
(3) by the large attachment face of mounting bracket and cylinder body is converted into the facet on bolt mounting holes, reduce the demand of working accuracy, indirectly reduced tooling cost;
(4) by cast out larger back-up block between mounting bracket and cylinder body attachment face and car load attachment face, thereby ensure the intensity and toughness of whole mounting bracket, improved the reliability of mounting bracket.
(5) by increasing the boss setting of mounting bracket bolt attachment face, make to form gap between cylinder body attachment face and mounting bracket, add cellular structure, make to form between cylinder body end face and mounting bracket mobile air layer, the vibration having produced while having reduced engine operation and noise transfer, to car load, have promoted the NVH performance of car load.
